Lette-rs Patent No. 96,520, dated Nocmnber 2, 1869.

IMPROVEMENT IN WBIGHING-'scanna The Schedule referd to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, J oHN WEEKS, of the city of Bulfalo, in the couiity of Erie, and State ofNew York, have invented certain new and useful Improvements in \Veighing-Srales; and 1 do hereby declare that the following is a full and exact d escriptiou thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a side elevation, and

Figure 2, an end view of the beams, showing their relative positions.

Like letters of reference indicate corresponding parts in both figures.

. My invention consists in providing and also in arranging on a weighing-scale four (4) or more beams, and also in their graduations to indicate not only pounds, tous, &c`.,but also bushels of grains or other commodities, each beam to answer a single or double purpose, as may be. desired, and all supported by one fulcrum, and employing but one weighing-rod, and without the use of weights.

In the drawings- A A represent the scade-frame.

B indicates the main beam, suspended on the ordi- I nary fulcrum, a, with the weighing-rod l), as is usual in ordinary scales.

C represents another beam, :man ged somewhat back and above, and attached to the main beam B. It is thus arranged and placed -so that its graduations can be Areadily seen, and its poise (for indicating weight or bushels) as readily handled by the weigher. 'f

D'represents a third beam, attached just below and in front of beam B.

E represents the fourth and lowest beam, which is also attached to beam B, and occupies a position below, between that and the third beam D.

An implntantfeature in my invention is thus placing, as above described, the beams above and below each other.

lt is common to place two horizontal beams parallel to each other, but .lfbelieve myself to be the h'rst to apply four or more beams to a scale, and to place them above and below each other, as hereinbefore described.`

The object in using as many beams, is brieily this :A

ent kind of grain, which might result in the wrong weights heilig used, thereby involving trouble and loss. My met-bod does away with this.

Herein lies another essential feature of my invengtion, which is the employment and use of as many different beams as there are graiusto be weighed, (or other commodities,) which shall be attached to one fulcrum, and forming, in other words, a compound beam, hywhch the various kinds of grains, or other .commodities ot' one or various denominations, can be weighed, and their. weight shown in bushels, gallons, Sac., by a glance of the weigher at the beam or the same can be weighed without using weights, and doing away with the trouble and liability of mistakes in reducing pounds to bushels or some other denomination, by the use of my beams thus arranged and graduated.

To clearly explain the practical operation of and working of the different beams, by reference to the drawings, it will be seen that the poise7 c, on the main beam B, is marked for wheat, and the upper graduatons on the beam indicate bushels, and the lower, pounds.

For example, wheat, which weighs si\'ty pounds to the bushel, is being weighed, and the poise c, in its position, indicates ninety bushels, and a weight of five thousand four hundred pounds.

On beam G, the poise d is marked "corn," and its position indicates titty bushels, weighing three thousand pounds, each bushel of corn weighing fifty-six pounds.

On the beam D, the poise e is marked for oats, each bushel of which usually weighs thirtytwo pounds, the weight varying in some States. 1n its position, the. poise indicates ten bushels, or three hundred and twenty pounds.

On all these beams, each notch or mark indicates a bushel, the upper line or lines of ligures showing the number of bushels, and the lower, the weight. When desired, graduating-marks will be also placed on the lower face of the beams, and an additional indicator or pointer will be arranged on the lower inner side of the poise, corresponding to the upper point-er or index.

The lower beam E is graduated only to pounds, which will at all times indicate the odd pounds for each and all the other beams, so that not only the number ofthe bushels, but the exact weight in pounds can he seen at once by the weighexzand parties inter ested.

If desired, one or more of the main beams may be graduated to pounds, as well as bushels, or any other.

denomination, as before stated, or, if preferred, to pounds alone, so as to indicate the hundreds and thousands, or tous on the main beams, and the odd pounds to be taken from the lower beam, graduated t0 pounds, as in other weighing.

Any varia-tion or combination that may be desired, can be made. The beams can either be used singly or together.

These improvements will prove of great value to those engaged in the grain-trade, especially large establislnnents, such as elevators, mills, SLG.

1t will prove of equal value in weighing coal at the mines, or for use in clieese-liwtories.

Whatfl cla-im as my invention, and desire to secure by Letters Patent, is'- As an improvementin grain-scales, the diagonal arrangement. or spread above and below the main beam B of the series of beams O D E, the beams B G D designating both weight and measure, but of different capacities, and the beam E being the unit-beam ther -oi', all beams having a common l'ulerinn, and by the diagonal arrangement exposing their faces simult-aneonsly to view from a connnon stand-point, as and for the. purpose set forth.

In witness whereof, I have hereunto signed my name, in the presence of two subscribing witnesses. JOHN WEEKS.
